The ATM AAL 3/4 protocol provides for reliable end-to-end transmission of SAR and CPCS PDUs, as well as multiplexing of multiple data streams on the same virtual connection, in ATM networks. (a) Assume that AAL 3/4 is being used and that the receiver is in the idle state. Two blocks of user data are then transmitted as two separate sequences of SAR PDUs. Given that the EOM SAR PDU of the first sequence is lost, will this error be detected at the receiving end and, if so, how will it be detected? If this error can be detected in more than one way, be sure to enumerate each detection method.
